A supermoon occurs when a full moon coincides with the perigee of the moon’s orbital cycle. A perigee is the point at which the moon moves closest to the Earth during orbit. Because the orbit is not a perfect circle, this means the moon typically sits anywhere between 252,000 and 226,00 miles from the earth.

That's a lot of science for this guy to wrap my head around.

I just know from life experience anytime you add the word super to anything it makes it more awesome!
